Join the numbers and get to the 256 tile!
How to play: Use your arrow keys to move the tiles, G key to rotate, hold 1, 2 or 3 to hidden layers,. When two tiles with the same number touch, they merge into one!
Special tiles:There are 'bonus' tiles. They have different colors from normal tiles and can only be merged with same one. Both tiles will disappear after being merged. They are not really bonus tiles. I added them just to increase difficulty. Since the 3D version has more tiles and more directions, it's much easier than the normal version if there's no traverse. Do you have any good idea?
